Hi All, I presented a webinar yesterday via DBEI (Digital Built Environment Institute) with some of my personal thoughts and observations on the topic of the infrastructure extension to IFC. This included some of the changes within the Release Candidate Standard, as well as some research into comparisons with using existing schema releases for representing linear infrastructure geometry (ie a 56KB IFC4x1 file can result in a 100MB proprietary file if the intelligence can’t be preserved). Also some insights into some work we’ve been doing on efficient downgrade of an IFC4x file. This webinar is available on the free tier of DBEI for the next 7 days, if you’d like to watch it you can register on this link.

Yes, registration on the site is a challenge:) I am wondering that pylon and deck are spatial elements rather then physical. Road application I am looking in now treats road parts as physical elements, and not sure I conceived how to map it with IFC. It seems we have some entities with dual nature and it may produce some issues… Where we stop ‘aggregate’ and start ‘contain’ ---

Why don’t we make it just concrete and steel ‘shapes’. That’s whats being praticed. ---

Click on the login button in the top right corner and sign up for a free DBEI account. Then you should be able to register for it, and click on the More Info button. ![200716 view webinar](https://us1.discourse-cdn.com/flex016/uploads/buildingsmart1/original/2X/a/ab1c60247598b47b1ebf2f975b81db701e98f4cd.png) ---

Hi Jon, Thanks for the information. I managed to register and log in to DBEI but I’m still not able to find the more info button. Here’s what I see: ![image](https://us1.discourse-cdn.com/flex016/uploads/buildingsmart1/original/2X/3/318f7173c2a31e0987b5a875ebdd7ca4959de4c4.jpeg) How can I solve it? Thanks. Roberto
